为什么要监听收款？那是因为现在还有人在使用微信的收款码、商业码、赞赏码实现免签支付，这类实现方法的最终方案还是监听收款结果。

技术原理

通过Python实时解析微信电脑版控件的文本内容来获取信息。不需要Hook和抓包，也不是走任何的协议，就是非常简单的界面信息获取和解析。

如何使用

1. 登录电脑版微信；
2. 找到微信支付公众号；
3. 双击，让微信支付公众号单独显示，如下图；
4. WxPayPcNotify.py修改你的接收通知的Url；
5. cmd运行WxPayPcNotify.py即可开启监听。

接收支付结果通知

WxPayPcNotify.py监听到收款通知后，会向你服务器POST三个参数：

amount：收款金额
sender：微信昵称
timestamp：到账时间

nitify.php示例

<?php
    
    // 收款金额
    $amount = trim($_POST['amount']);

    // 微信昵称
    $sender = trim($_POST['sender']);

    // 到账时间
    $timestamp = trim($_POST['timestamp']);

    // 编写你的逻辑

?>

代码

WxPayPcNotify.py

import re
import time
import uiautomation as automation
import requests

last_matched_info = None

def explore_control(control, depth, target_depth):
    global last_matched_info
    try:
        name = control.Name
        if name:
            if depth == target_depth:
                # 匹配收款金额信息
                match = re.search(r'收款金额￥([\d.]+)', name)
                if match:
                    global amount
                    amount = match.group(1)
                    last_matched_info = f"收款金额: ￥{amount}, "

                # 匹配来自、到账时间信息
                match = re.search(r'来自(.+?)到账时间(.+?)备注', name)
                if match:
                    global sender
                    sender = match.group(1)
                    global timestamp
                    timestamp = match.group(2)
                    last_matched_info += f"来自: {sender}, 到账时间: {timestamp}"
                return
        # 递归处理子控件
        for child in control.GetChildren():
            explore_control(child, depth + 4, target_depth)
    except Exception as e:
        print(f"发生错误: {str(e)}")

            # 向服务器发送请求
            send_http_request(last_matched_info,amount,sender,timestamp)

    else:
        print("无法获取到窗口，请保持微信支付窗口显示...")
    return prev_info

    # 接收通知的Url
    server_url = 'https://www.yourdomain.com/notify.php'

        response = requests.post(server_url, data={'amount': amount,'sender': sender,'timestamp': timestamp})
        # 通知成功
        # print("通知成功")
    except Exception as e:
        # 通知失败
        print(f"通知服务器失败...: {str(e)}")

def main():
    global last_matched_info
    prev_info = None
    try:
        # 获取微信窗口
        wechat_window = automation.WindowControl(searchDepth=1, ClassName='ChatWnd')
        prev_info = process_wechat_window(wechat_window, prev_info)

        time.sleep(2)
